A major Atlantic Ocean current system that regulates global climate has been slowing down for nearly 20 years. New research provides direct evidence of the decline across a wide area of the North Atlantic.

Scientists at the University of Miami Rosenstiel School of Marine, Atmospheric and Earth Science led the study. They analyzed data from four seafloor monitoring arrays stretching from the tropics to mid-latitudes. The instruments measured pressure, temperature, and currents to track deep ocean flows below 1,000 meters.

Cleaning up air pollution could weaken vital AMOC ocean current

New research shows that efforts to reduce air pollution in Europe, North America and East Asia could accelerate weakening of the Atlantic Meridional Overturning Circulation. The ocean current plays a key role in regulating Europe’s climate. Scientists used multiple climate models to assess the impact under continued high greenhouse gas emissions.

Study links Atlantic cold blob to weakening ocean currents

A patch of cooling ocean south-east of Greenland, known as the cold blob, is likely caused by a slowdown in the Atlantic Meridional Overturning Circulation, according to new research. The findings add to concerns about potential future climate impacts in Europe and beyond. Scientists remain divided on the exact causes.

El Niño has 80 percent chance of developing by September

Scientists forecast an 80 percent likelihood that an El Niño will form by September, with most models pointing to a moderate event. Some simulations indicate the possibility of a much stronger episode. Global warming is expected to intensify the effects of any such occurrence.

Researchers propose bering strait dam to stabilize amoc

A team of Dutch scientists has presented simulations showing that a massive dam across the Bering Strait could help prevent the collapse of the Atlantic Meridional Overturning Circulation. The proposal was outlined at a major geoscience conference in Vienna this month.

Scientists map deep mantle deformation linked to ancient tectonic slabs

Researchers have created the first global map showing how Earth's deepest mantle is deformed, primarily in regions where ancient subducted tectonic slabs reside. Using over 16 million seismograms, the team confirmed patterns predicted by geodynamic models. The findings, published in The Seismic Record, offer new insights into mantle flow near the core-mantle boundary.
